摘要:
A method for manufacturing an insulator for a spark plug includes a molding process of forming a cylindrical molded product having an axial hole that extends in a direction of an axial line, by means of injection molding using a mold that has a columnar cavity therein and a bar-shaped member disposed in the cavity and extending in the direction of the axial line. In this method, the molding process includes an injection step of injecting a material containing a ceramic. In the injection step, the material is injected into the cavity from a plurality of injection openings that are opened at an inner circumferential surface, of the mold, that forms the cavity. The plurality of injection openings include two or more injection openings located at different positions in the direction of the axial line, or two or more injection openings located at different positions in a circumferential direction.

A casting machine (722) for fabrication of precast concrete structural members (1) is disclosed, which includes side walls with integrally formed end dams (784) which are movable from an open position (78) to a closed position (80), and a bottom casting surface (88), where the bottom casting surface (788) and side walls (784) serving to form a mold (812) surrounding a cavity (108) configured to contain wet concrete (26). Concrete (26) is pumped into the cavity (108) when the self-releasing mold (812) is in closed position (80). The side walls (784) are automatically movable to the open position (78) when the concrete (26) has solidified so that a precast concrete structural member (30) is automatically released from the self-releasing mold (812). Also disclosed is a precast modular system (710) for automated concrete structural member fabrication, which includes a concrete mixing system (716), a concrete delivery subsystem (764), a block transport subsystem (720), and a plurality of casting machines (722), where each casting machine (722) includes a self-releasing mold (812).
摘要:
A vertical shear wall system including vertical metal framing members, for example, C-joists, U-joists, open web joists, or other metal frame systems that support a reinforced, lightweight, dimensionally stable SCP panel. The shear wall system is non-combustible, water durable, mold and rot resistant, termite resistant and is capable of resisting shear loads equal to or exceeding shear loads provided by plywood or oriented strand board panels. The panels employ one or more layers of a continuous phase resulting from the curing of an aqueous mixture of inorganic binder, for example, calcium sulfate alpha hemihydrate, hydraulic cement, an active pozzolan and lime. The continuous phase is reinforced with glass fibers and contains lightweight filler particles, for example, ceramic microspheres.

An apparatus for manufacturing simulated stone products is provided. The apparatus includes a mold having mold cavities. The mold cavities have a first section and a second section that intersect to form a cavity angle. A hopper is configured to introduce castable material into the mold. The hopper and the mold are moveable with respect to each other, enabling them to be selectively engaged with each other. The hopper includes a first funnel wall configured to contact the top of the first mold cavity and to introduce castable material into the top opening of the first section. The hopper has a second funnel wall configured to contact the second section and act as a barrier to close the top opening of the second section of the mold cavity.

摘要:
An organic silicon polymer is infiltrated and charged into gaps in a matrix phase of a formed fiber fabric, and its airtightness is increased by (a) CVI infiltration process 2 for forming the SIC matrix phase on the surface of the fiber fabric formed, (b) pressurized infiltrations process 4 for pressurizing the organic silicon polymer in the direction operating pressure is applied to the fiber fabric during use and infiltrating the organic silicon polymer into gaps in the aforementioned matrix phase, and (c) heating process 5 for heating the infiltrated fiber fabric at a high temperature. Thus, airtightness can be increased quickly, and fired work can be applied practically even to thrust chambers etc.
摘要:
Compositions, methods, and systems for manufacturing articles, particularly containers and packaging materials, having a highly inorganically filled matrix. Suitable inorganically filled mixtures are prepared by mixing together an organic polymer binder, water, one or more aggregate materials, fibers, and optional admixtures in the correct proportions in order to form an article which has the desired performance criteria. The inorganically filled mixtures are molded to fashion a portion of the mixture into a form stable shape for the desired article. Once the article has obtained form stability, such as by heating to remove water by evaporation, the article is removed from the mold and allowed to harden to gain strength. The articles may have properties substantially similar to articles presently made from traditional materials like paper, paperboard, polystyrene, plastic, or metal. They have especial utility in the mass production of containers, particularly food and beverage containers.
